This looks great! I do a lot of http stuff on the esp and I find myself doing a lot of copy and pasting from older projects to get it working

That looks fine (it's the same as I mentioned above)If you are having issues I would recommend getting one of the basic examples of px matrix working first, such as pixel time. not point complicating the troubleshooting by adding wifi and NTP into the mix.

Thats so cool! great improvement!

Looking good!

Right now yes, but I am working on a solution that will not require soldering.

Thanks for sharing awesome that you were able to get it up and running ! Yeah photographing these displays is my kryptonite :D

There is a wiring diagram in the pictures section and the wiring table in the text. Is there something else I can provide?

Thanks DarkHours, delighted you got it working!

My code is for the esp32 and that's an esp8266.I tried doing an esp8266 version but it was crashing for me.

Hey Rud, looks great! Is this using my arduino Spotify library?If so I have made some changes to it recently that probably greatly improved it's stability so make sure to update it!

I can't guarantee that any matrix panel will definitely work, as they have changed them in the past, but I have bought a panel from that link within the last 3 months and it has worked. That message has been there for about 2 years :)

Thanks for the feedback, It supports up to 30V and can supply up to 3A without a fan.I've updated the Instructable with the details around what this particular module supports in "Components for the Build step"As for the comment about the ATX supply, for this power supply module (ZK-4KX), It wouldn't make a difference for me anyways, as even my USB-C power bank (60w) is able to provide more power than the max the module can support (35W normally or 50w with cooling)

I am expecting parts for more stock to come next week, so I recomend signing up to be notified on Tindie!

A fix for this has been made in newer version of PxMatrixInfo about it here:https://github.com/2dom/PxMatrix/issues/119

yes it should work, althought I haven't personally tried!

The Motor shield has the ability to reverse the voltage applied to each leg of the motor. So connecting VCC to one terminal on your motor and ground to the other will make a motor spin one way, and connecting it the opposite way around will make it spin the other. The code looks after swapping it around when you press the drive button or the reverse button.

Hey Jonathon, really nice instructable! My daughter is still in a cot for the moment, but moving to a bigger bed is pretty soon and I think we'll need something like this!I'm a huge fan of the ESP8266, it would be a great choice for a project like this. I recommend going for something like the Wemos d1 mini, you can get them from Aliexpress for about $3 delivered, they have a built in USB to serial converter and have 9 digital GPIO pins.You wouldn't even need an RTC anymore if you didn't want it as you can get the time from an NTP serverI have a WIP project of an alarm clock using an esp8266 if you wanted to check it out. It fetches the time from the internet, automatically looks after DST and you can set the alarm from a web interface (really basic). Hopefully some of it is useful to you…

I also worked on it mostly on live streams, but I don't know if its worth going back over them! https://www.youtube.com/playlist?list=PLbd5_U5QzQgYuUgvO5uwiekRx3ljlP8Jg

That looks great Damo! Thanks for sharing!

Interesting, thanks for sharing that!

The library supports chaining two displays together not sure if it supports more than that

The response from Google maps API gives step by step instructions like that, but I never included it in the Arduino API library because it's really too much data to be able to handle on the Arduino (during testing I saw a 20,000 characters of text in this field), you would also have the problem of not knowing when you reach B in your example, so you wouldn't know when to change to the B to C instruction

I think you just need to send two payloads to each light, one to start the rainbow pattern and then one to make the brightness be 75% (which I believe you are right in saying is %<brightness>)Remember to do the same for button 2 in your example, but set the brightness to be full: %<255> I think should do it

I believe they support up to 8 no problem, there is one issue with the 4 in 1 modules, they dont work with the standard version of the library, the letters scroll from top to bottom of each segment rather than from left to right.This is a modified version of the library where the author has added a display.setRotation(true) option that should fix the rotation for those displays

Thanks! Really appreciate it!

I haven't tried anything like that yet. I doubt you would be able to get anything close to good frame rate out of it though. If you check out the readme of the library you can see where the author has a video running at 10FPS using an esp32, but I believe it is hosted locally.I have been playing around with making a webinterface that allows you to draw pictures onto the display which is pretty nice! https://github.com/witnessmenow/ESP8266-Led-Matrix-Web-Draw

Thanks Mike!

It works for sure!

Awesome work Tobias! Definitely going to try this out on my 64x32 version

Awesome project Igor!

Hey, If you use the UniversalTelegramBot library it supports reply keyboards, might save some typing!https://github.com/witnessmenow/Universal-Arduino-...

Yeah, the button options at the bottom of my picture.

I have a library written for the coinmarketAPI if you wanted to check it outhttps://github.com/witnessmenow/arduino-coinmarket...It also avaible on the arduino library manager

Your welcome, glad you liked it!

I beilieve they have updated the name of the maker channel to be "webhook" it should work the exact same.

Yes i believe so, I'm open for correction but I don't this it manipulates the signal in at all, I believe it uses the signal in as an input to a transistor once the input is high enough to trigger the transistor you should get LV lever signal (3.3 in our case) outI haven't tested this but I'm 90% sure that's how it would workThe great thing about the adafruit stuff is it is all open source so you could actually take a look at the schematic to see what they use to make a sensor or display tolerant

Nice guide!I made a similar one using the Ikea lamp you link to an a couple of adapters for a gopro, one 3-way pivot connector (with thumb screw) and a go pro to 1/4" adapter, price in total for both was about $3 delivered from Aliexpress. The only other thing i needed was a nut or a couple of washers to separate the part that connected to the arm.Might be useful to someone!

Whoops didn't notice that big piece of husky hair in focus there!

This looks awesome, Thanks for sharing!

Thanks Gary!I haven't been too bad with customs recently thankfully!Yeah both pieces of software in this guide are so great, this project should have been so much harder than it was! It's great that you thought of a use case for them!

Hi RomanB53, I just replied to Daniel there with the problem (its the chip). The solution is to get a different board, but I have not found a good source for them yet.

Hi Daniel,Really sorry about the delay being so long, I didn't know the answer at the time you posted and forgot to update here when I figured it out.There is two different styles of HC-05/06 boards and one of them does not work.https://camo.githubusercontent.com/baa7aa8773d4f22e5acfa1d45a0d538bf782bba3/68747470733a2f2f692e696d6775722e636f6d2f3130674d556d552e706e67Unfortunately there doesn't seem to be a great way of ensuring which one you get as I bought 3 modules from different sellers in Septempber, all the listings looked like the good version but two were the bad ones. Maybe it is worth contacting the sellers asking which ones they are

Awesome that you made one! I would love to see a photo of it.Sorry about the API key mix up, you are right it should be a directions key! I have updated it now.

I know I replied on twitter and YT but I really love seeing this, thanks so much for sharing!Good tip about Michaels, I really like to colour of your frame actually. I think any kind of a box frame like this should do, just somewhere to hide the wiring at the back.I updated the part with the API keys, thanks for letting me know.

Nice to see Mr Arduino Json floating around! Thanks for the library!

I have completed the Instagram library now :)Video about it here:https://www.youtube.com/watch?v=ssceP406eYk

I made a video on my the Instagram library Becky is using if you want to check it out!https://www.youtube.com/watch?v=ssceP406eYk

Working with the twitch API is on my todo list, just need to find the time to look at it!The Instagram library only took a few hours so hopefully twitch wont be too hard.I thought it would also be nice to be able to fetch sub notifications and donations, but I'm not too familiar whats available in the API or how it works (I'm sure this is)

Hey MarcelT36Your welcome, sorry its not working out for you!I'll program it up again over the next couple of days and make sure the sketch is the correct one, I didn't have anymore speaker modules when writing this up so I couldn't test so I just had to trust my sketch naming!I've since got some so I'll try it out and get back to you. How are you powering the project?

thanks!

This is awesome Igor, well done!

Awesome project Nikodem, well done!

I'd imagine it's a challenge ok! We have two large dogs (husky/golden retriever cross and a husky) so anyone with restrictions is definitely ruling us out!Ha, I've never even had an Instagram account! I'm actually not really into social media at all, kinda have gone more into the walled garden approached of Whatsapp and Telegram groups with friends etc. I basically never use Facebook and I'm only recently trying to get into twitter. My wife is the same so just for privacy reasons we don't post any pictures of our daughter up anywhere for the time being. We are only more than happy to share dog pics (they'll hopefully starring in a project video soon :) )That's on my longlist! I'll get it done at some stage!In the meantime the best I can offer you:Twitter: https://github.com/witnessmenow/a…
